* `startOfDay(TimeInfo): TimeInfo` returns a new `TimeInfo` representing midnight at the beginning of the given day. * `startOfWeek(TimeInfo, WeekDay): TimeInfo` returns a new `TimeInfo` representing midnight at the beginning of the first day of the week. By default Monday is used as the start of the week (to be consistent with `times` view of the day order), but the user can pass in any other day to "start" the week. Because this find the start of the *current* week, the returned `TimeInfo` will always be a date in the past or present, never a date in the future.
